Abstract
An improved light barrier optical module including a system of one or more light blocking partitions. The partitions have different sized orifices configured to reduce the effects of parasitic light rays which would otherwise interfere with the reliable operation of the module. The module is suitable for both the transmission and reception of light barrier beams and for production using injection molding.
